Take a peek. (IMG:style_emoticons/default/drooley.gif)

This is a brand new 2.5 shortblock that is dressed with the old parts from my 2.0. The engine is now complete and should be installed by next weekend. I will do my best to take a little video of the maiden voyage.

Oh yea, I forgot to add...

The shortblock is brand new shipped from Subaru to my door for $1,870.00 and I swapped the old 2.0 shortblock for the labor to build the new motor (IMG:style_emoticons/default/piratenanner.gif)

That is not bad at all! If you buy a beat up 2.0 liter and do this swap, it might make great sense... (IMG:style_emoticons/default/idea.gif)

(IMG:style_emoticons/default/wub.gif) Beautiful! You've inspired me to step away from the computer and go work on my subie conversion - into a Westy.

So I understand correctly...... Basically your old motor was a USDM WRX EJ20 Turbo and you can swap the whole shootin' match over to that factory shortblock and have a basically new EJ25 turbo?

My son and I hotrod his 05 STI. A 2.5 will have more torque but it isn't the same as a factory 2.5 turbo. 2.5 wrx and 2.5 sti have differences that translate to different torque and hp ratings. 2.5 Sti has acvs and older 2.0 wrxs don't. Sti has bigger turbo, bigger injectors, bigger IC, bigger cams, and quite a bit more better ecu control also higher redline ecu. 2.5 STI has forged rods but the pistons are a little brittle for heavy tuning advances. A 2.5 is a great start for a 2.0 rebuild but it will run out of breath at a lower rpm than the real sti due to the wrx cams and no active cam control.

I like the 2.0 or 2.2 closed deck blocks hopped up because they have less low end torque and when boosted over 25 psi will make lots of power. A 2.5 STI mildly retuned will push the limits of the 914 tranny. With the 2.5 a good path would be to use the suby tranny converted to front wheel drive and with the OBX LSD. With only rear wheel drive and 9 inch tires that might hold up and be cost effective.

Your motor really looks nice and new.

I realize just because its 2.5, its not STI spec. But still, thats pretty cool you can just dump your short block and bolt your ancillary pieces on a factory 2.5 and get the extra displacement.

Even though it may run out of breath early, I would imagine you are gaining some torque?

Yes but torque is what breaks trannys not hp up high.

BJ had done this (2.5 with 2.0 externals) and was over 400HP at the crank.

Yes.

You can just buy the 2.5 STI shortblock and put all of the 2.0 crap on it and build it as a Hybrid Subaru 2.5 with 2.0 ancillary's. I am expecting a 75 hp gain and about 100ft/tq gain. And I will of course dyno it and let you all know the real numbers for my engine. It should be installed tonight!!!!

It is installed and running!

Just need to take my radiator in to have them check it for leaks and break in the motor. Then I can turn up the boost and haul booty.

That was your car I was reading about in Excellence last night. Made it seem really tempting to go buy a roller and throw a wrx motor in it.

Yup, that is the one...

I would recommend to anyone to do this swap. It is a real kick in the pants to knock the crap out of new 996 and 997's.

BTW... does my avatar look familiar? It is very similar to the spread pic in the article.

Yeah the picture looked familiar. I like the idea of having 911 power for honda civic prices.

I spent 10 grand building a honda civic motor with 350whp. Could have tuned it to over 500 but 350 seemed like enough. To get that kinda power with a 911 motor would just be way to expensive.

I would be interested to know how much has this conversion cost. When you compare this conversion to a 6 conversion it appears to be way more cost effective but I would like to know how much have you invested.
